<5. the operation > of (in the time that pairing arranges) in the time that identifying information exchanges
Be described in the operation between the display unit 10 and audio output device 30 of correspondence (pairing), in the time that the pairing of exchange identifying information (to installing unique identifying information, such as device ID) arranges to Figure 18 referring now to Figure 12.As shown in figure 12, there is the situation of N source device 20-1 to 20-N by describing the source device that can be connected to for display unit 10 and audio output device 30.
Figure 13 shows the flow process of the pairing setting operation between display unit 10 (stay of two nights 1) and audio output device 30 (stay of two nights 2) to the flow chart of Figure 15.
At step ST100, that the pre-FEFO of display unit 10 connects is required, with the authentication tasks that is connected of source device, with make can be on network being connected of execution and source device freely.In this case, display unit 10 is carried out the connection authentication tasks of the source device (N source device 20-1 is to 20-N) of the predetermined number that can be connected to relevant display unit 10.
Similarly, audio output device 30 start to match before setting operation the pre-FEFO of step ST300 connect required, with the authentication tasks that is connected of source device, with make can be on network being connected of execution and source device freely.In this case, audio output device 30 is carried out the connection authentication tasks of the source device (N source device 20-1 is to 20N) of the predetermined number that can be connected to relevant audio output device 30.
At step ST101, the sign on of the pairing setting of display unit 10 based on from user and the setting operation that starts to match.At step ST301, the sign on of the pairing setting of audio output device 30 based on from user and the setting operation that starts to match.In other words,, in the time beginning being set from user's instruction about the pairing of display unit 10 and audio output device 30, start the pairing setting operation in two devices.
There is pairing and button and user are set press pairing when button is set when supporting that the device of pairing is each, can realize from sign on user, that the pairing of each device is arranged.The in the situation that of display unit 10, can realize the sign on that pairing arranges by the item that this state setting is provided to the setting option of control inputs GUI.The in the situation that of audio output device 30, can provide pairing execution pattern to realize the sign on that pairing arranges by arranging in parameter in menu.User can determine corresponding device and by by user directly the function mounting of instruction start to match setting operation to each pairing destination apparatus.
Display unit 10 starts to match setting operation at step ST101, then determines whether to exist paired data at step ST102.Paired data be such as obtain by the matching operation in past, with the device ID of another device corresponding to oneself device, and in addition, such as the identifying information of logical address of another device obtaining after corresponding with identifying information and so on.
If there is paired data, display unit 10 is wiped paired data at step ST103.If keep old paired data in the time that the device about having matched etc. re-starts pairing, remove this data.
Display unit 10 proceeds to the processing of step ST104 after the processing of step ST103.If there is not paired data at step ST102, display unit 10 proceeds to the processing of step ST104 immediately.
Similarly, audio output device 30 starts to match setting operation at step ST301, then determines whether to exist paired data at step ST302.If paired data exists, audio output device 30 is wiped relevant paired data at step ST303.Audio output device 30 proceeds to the processing of step ST304 after the processing of step ST303.If there is not paired data at step ST302, audio output device 30 proceeds to the processing of step ST304 immediately.
At step ST304, audio output device 30 arranges the state of " in pairing arranges ", etc.At step ST305, audio output device 30 is connected to that (information source j) with the Arbitrary Information Sources device in the connected source device of predetermined number that connects authentication tasks and carry out at step ST300.The source device connecting also needs to be connected to display unit 10 simultaneously, when therefore source device need to be supported with multiple device, is connected.
At step ST104, after this display unit 10 proceeds to the processing of step ST105 after waiting for the scheduled time.Display unit 10 is by waiting for the scheduled time, and (source electrode is the processing after starting afterwards step ST105 j) to be connected to Arbitrary Information Sources device at audio output device 30 at step ST305.
At step ST105, display unit 10 is searched for the connected source device of carrying out to connect authentication tasks at step ST100 on network, and lists whole devices.The number of the source device of listing is maximum information source.Display unit 10 arranges i=0 at step ST105.
Display unit 10 is listed and can be connected source device at step ST105, and starts to be connected to successively source device from list top.Display unit 10 can also be connected to the source device of finding successively and not create list.After being connected to source device, display unit 10 inquires that whether connected source device also set up and being connected of audio output device 30.If do not set up and being connected of audio output device 30 from source device report, display unit 10 is removed this connection, is connected to next source device in list, and the existence being connected of investigation and audio output device 30 similarly.Repeat this process to make display unit 10 can specify the source device being connected with audio output device 30.
After specifying the source device that is connected with audio output device 30, display unit 10 then by source device to connected audio output device 30 inquiry states.If do not report the state of " pairing arranges " from audio output device 30, display unit 10 is removed and being connected of source device, and is connected to next source device in list.Specify thus the source device connecting with the audio output device 30 (namely, thering is the audio output device 30 of the state of " in pairing arranges ") of pairing Offered target.
In other words,, after step ST105 lists and can connect source device, display unit 10 increases progressively i at step ST 106.Display unit 10 determines whether the maximum information source of i > at step ST107.If not the maximum information source of i >, this means the source device that still has display unit 10 to be connected to.
If be not the maximum information source of i > at step ST107, display unit 10 is connected to i source device at step ST108 (information source i).At step ST109, display unit 10 inquires source device that (whether information source i) is also set up and being connected of audio output device 30.
Display unit 10 then at step ST110 based on from source device, (information source report i) determines (whether information source i) has and being connected of audio output device 30 source device.If (information source i) is not connected with audio output device 30 source device, and display unit 10 turns back to the processing of step ST106, and proceeds to the processing about next source device.
If (information source i) has and being connected of audio output device 30 source device, and by source device, (information source is i) to connected audio output device 30 inquiry states at step ST111 for display unit 10.Display unit 10 response based on from audio output device 30 and determine the whether state in " in pairing arranges " of audio output device 30 at step ST112.
If the not state in " in pairing arranges ", display unit 10 turns back to the processing of step ST106, and proceeds to the processing about next source device.If in the state of " in pairing arranges ", display unit 10 specify source device (information source i) as with the source device that is connected of audio output device 30 of pairing Offered target, and after this proceed to the processing of step ST113.
(j) afterwards, audio output device 30 proceeds to the processing of step ST306 to information source to be connected to Arbitrary Information Sources device at step ST305.At step ST306, audio output device 30 determines whether to make the inquiry about state from display unit 10.If do not make the inquiry about state, make at step ST307 that (information source j) starts whether to have passed through determining of constant time and overtime (TimeOut) from being connected to source device, if do not have overtimely, audio output device 30 turns back to the processing of step ST306.
If make the inquiry about state at step ST306 from display unit 10, at step ST308, by source device, (it is the response of " in pairing arranges " that information source j) does well to display unit 10 to audio output device 30, then proceeds to the processing of step ST309.
As mentioned above, in display unit 10, having specified the source device that the audio output device 30 of pairing Offered target is connected to, (information source i) afterwards, between display unit 10 and audio output device 30, exchange identifying information, such as to installing unique identifying information, comprise device ID etc.Here the identifying information of exchange is assumed that " device ID ".
In other words, at step ST113, by source device, (the information source i) request of dispensing device ID arrives audio output device 30 to display unit 10.Audio output device 30 is the request from display unit 10 receiving system ID at step ST309.Display unit 10 then step ST114 and audio output device 30 step ST310 by source device (information source is i) about switch ID each other, and in the own memory installing etc. storage device ID.Realize by this way pairing setting, namely, the exchange of identifying information.
But user may have in the end check pairing setting.For example, in this case, send the audio frequency such as test tone and so on from audio output device 30, and in display unit 10, show that certain message checks operation with request user, to make carrying out inspection.If will carry out user's inspection operation, complete pairing setting, and audio output device 30 be removed the state of " in pairing arranges ".
In other words, display unit 10 is obtained the device ID (identifying information) of audio output device 30 at step ST114, and the processing of then carrying out user at step ST115 is to carry out the inspection about pairing, such as display message.Then display unit 10 determines at step ST116 whether user has carried out " OK " operation that pairing checks.If user has carried out " OK " operation, display unit 10 completes pairing setting at step ST117.If user does not carry out " OK " operation, display unit 10 proceeds to the processing of step ST118.
Audio output device 30 obtains the device ID (identifying information) of display unit 10 at step ST310, the processing of then carrying out user at step ST311 is to carry out pairing inspection, such as the audio frequency of output such as test tone.Then audio output device 30 determines at step ST312 whether user has carried out " OK " operation that pairing checks.If user has carried out " OK " operation, display unit 10 is removed the state of " in pairing arranges " at step ST313, and completes pairing setting at step ST314.If user does not also carry out " OK " operation, audio output device 30 proceeds to the processing of step ST315.
In the connection authentication tasks of display unit 10 and audio output device 30 (step ST100, step ST300), also consider two devices not in to same source device can connection status situation.In this case, when wait for the status enquiry from display unit 10 when audio output device 30, even or this situation of overtime identification in the time that display unit 10 is connected to whole source device in list and also fails to find the audio output device 30 of pairing target.In this case, can notify the message of impelling user to connect authentication check.
In other words,, when in the maximum information source of step ST107i >, display unit 10 proceeds to the processing of step ST118.At step ST118, display unit 10 shows and impels the message that connects authentication check (authentication error inspection) to user.Audio output device 30, when overtime in step ST307, proceeds to the processing of step ST315.At step ST315, audio output device 30 is by opening such as light-emitting component or the output audio of LED and so on impel and connect authentication check (authentication error inspection) to user.
Figure 16 is illustrated in display unit 10 for finally impel the demonstration example of the message of pairing inspection to user.Display unit 10 shows message as shown in figure 16 at step ST115, and impels user on remote controller 106, to input [OK] button or [cancellation] button.Audio output device 30 is exported the exemplary audio such as certain test tone and so on simultaneously.Visual GUI is provided in display unit 10 and provides sense of hearing exemplary audio from audio output device 30 so that user can consciousness ground (perceptually) testing fixture pairing whether as desired.
Figure 17 illustrates that user checks the precedence diagram of an example of the result treatment of application.First, as shown in figure 17, in the time that the operation detection unit 178 by display unit 10 detects user's the operation of " pairing confirm " (S702), the communication unit 166 of display unit 10 sends order < and has matched > (9) (information source i) and ask relaying (S704) to source device.
< has matched the >< stay of two nights 1 address >< source address >< stay of two nights 2 address > (9)
In order, < has matched in >, and < has matched >, and to indicate it be the order for having notified pairing.In order, < has matched in >, the < stay of two nights 1 address > represents the address of order issue information source (display unit 10), < source address > represents the (address of source device (information source i)), and the < stay of two nights 2 address > represent the address of the order target stay of two nights (audio output device 30), destination of order.
Having received order < has matched the source device of > (9) (information source relay process unit 278 i) has matched audio output device 30 that > (10) sends to the stay of two nights of order target for relaying (S706) by order <.
< has matched the >< source address >< stay of two nights 2 address > (10)
